[707] So too, bhikkhus, here some wise, competent, skilful bhikkhu dwells contemplating the body in the body (kāyānupassanā), ardent (ātāpī), clearly comprehending (sampajāno), mindful, having removed covetousness and grief regarding the world. As he dwells contemplating the body in the body, his mind (citta) becomes concentrated, the corruptions (upakkilesā) are abandoned; he apprehends that sign (nimitta). He dwells contemplating feelings (vedanā) in feelings … He dwells contemplating the mind in the mind … He dwells contemplating dhammas in dhammas, ardent, clearly comprehending, mindful, having removed covetousness and grief regarding the world. As he dwells contemplating dhammas in dhammas, his mind becomes concentrated, the corruptions are abandoned; he apprehends that sign. That wise, competent, skilful bhikkhu, bhikkhus, is both one who gains pleasant dwellings in this very life and one who gains [1] mindfulness (sati) and clear comprehension. For what reason? Because, bhikkhus, that wise, competent, skilful bhikkhu apprehends the sign of his own mind (citta).
